B'Suppose you are given a sequence S of k pairs of integers (a_1, b_1), (a_2, b_2), ... , (a_k, b_k) . You can perform the following operations on it: Each operation can be performed arbitrary number of times (possibly zero). Let f(S) be minimum possible x such that there exists a sequence of operations with total cost x , after which all a_i from S are pairwise distinct. Now for the task itself ... You are given a sequence P consisting of n pairs of integers (a_1, b_1), (a_2, b_2), ... , (a_n, b_n) . All b_i are pairwise distinct. Let P_i be the sequence consisting of the first i pairs of P . Your task is to calculate the values of f(P_1), f(P_2), ... , f(P_n) . The first line contains a single integer n ( 1 <= n <= 2 cdot 10^5 ) -- the number of pairs in sequence P . Next n lines contain the elements of P : i -th of the next n lines contains two integers a_i and b_i ( 1 <= a_i <= 2 cdot 10^5 , 1 <= b_i <= n ). It is guaranteed that all values of b_i are pairwise distinct. Print n integers -- the i -th number should be equal to f(P_i) . '...
